Solutions and Prevention Methods for Curled and Dropped Leaves When Growing Flowers in Summer

In the hot summer, besides being irritated by the scorching weather, you also have to worry about the delicate flowers at home. One moment you worry they are thirsty, the next you worry they are waterlogged, and you also worry about them being bitten by insects, or their leaves curling or dropping - it is even more worrisome than raising children, for fear they will grow poorly. So, what should you do when curled and dropped leaves appear when growing flowers in summer? What methods can solve it? What prevention methods are there?

1. Causes of and solutions for curled and dropped leaves when growing flowers in summer

Cause 1: Temperature too high. The summer weather is hot, and the water absorption efficiency of the flower's roots cannot keep up with the transpiration of the plant's leaves. The moisture in the leaves is lost in large amounts due to exposure to the sun, and the leaf stomata close over a large area to resist the sun exposure and reduce water loss, causing the leaves to wilt and curl.

Solution: You can use a spray bottle to mist the leaves, or water thoroughly in the early morning or evening, or move the flowers to a shady place. Never water at noon when the sun is strong. Once the flowers have sufficient water to absorb, they will immediately return to normal. However, not all flowers can withstand exposure to the sun. Some flowers cannot recover after sun exposure or are directly killed by it, while some flowers are hardly affected and instead bloom even better. Therefore, you should first understand the flower's tolerance for sunlight and choose a reasonable solution.

Cause 2: Dry air. Flowers all like a humid environment. If the air humidity is insufficient, the leaves will curl.

Solution: Often sprinkle water around the plants to increase air humidity.

Cause 3: Insufficient watering. Because flowers like a humid environment, if watering is missed or only half-watering is done, it will affect the flowers' absorption of nutrients. The leaves will be dull and lusterless, shrunken and curled leaves will appear, and in severe cases the leaves will turn yellow and fall off.

Solution: First water a small amount and spray water, and after the plant recovers, water normally. On ordinary days, keep the potting soil moist; on cloudy and rainy days, you may skip watering.

Cause 4: Overwatering. If plants are watered too much, long-term excessively wet potting soil will cause a lack of oxygen in the soil, make part of the plant's fibrous roots rot, hinder the plant's normal respiration and absorption of water and nutrients, and cause the leaves to turn yellow and fall off.

Solution: Immediately control watering, and often loosen the soil to keep the soil well aerated.

Cause 5: Insufficient fertilizing. Because flowers need to bloom, they all require sufficient fertilizer. If fertilizing is insufficient and nutrient elements are lacking, the leaves will be thin and weak, thin and yellow, and finally fall off.

Solution: Repot in time with new nutrient soil, and gradually increase fertilizer application.

Cause 6: Too much fertilizer. This will cause root burn, leading to yellowing leaves and leaf drop, and in severe cases root rot and death.

Solution: Immediately stop fertilizing and increase watering, or immediately take the plant out of the pot, wash the soil, and replant it in the pot.

Cause 7: Pests and diseases occur. Because summer temperatures are high, pests and diseases easily occur, making leaves prone to curling or yellowing and dropping. If pesticides for preventing and controlling pests and diseases are applied but the pesticide concentration is too high, or if the plant is polluted by toxic gases in the air, or if cold water is suddenly poured when the temperature is high, the leaves will become partially yellow and scorched, or even the whole plant will wither and die.

Solution: Use pesticides reasonably and eliminate air pollution sources; or mix soap and clean water in proportion and spray it on the insects, which can kill some soft-shelled pests.

Cause 8: Iron deficiency. When people lack iron, their faces turn yellow, and so do flowers. Some flowers that lack iron will get chlorosis, causing the leaves to turn yellow, dry up, and fall off.

Solution: Spray nutrients on the flowers, spraying them on the leaves; you can also mix white vinegar and water at a ratio of 1:500 and spray it on the leaves.

2. Methods to prevent curled and dropped leaves when growing flowers in summer

Method 1: Care in an air-conditioned room. For growing flowers, the environment is very important. Summer is hot, and keeping flowers in an air-conditioned room can help them escape the heat, but too much air conditioning is also not good. At this time, you should regularly spray a little water on the flowers, ventilate them, and occasionally let them see light, avoiding exposure to the sun. For sun-loving flowering plants, it is still better to let them get more sun.

Method 2: Shade care. Many flowers are not suitable for exposure to the scorching sun, so you can give them appropriate shade, such as moving the flower pots to a shady place; or provide appropriate scattered light, such as cutting off excess leaves; or sprinkle water on the ground to lower the temperature and increase air humidity.
